When marked reports are compared it is unclear whether marks and their similarities are the same
I suppose to highlight somehow cases when marks or similarities are different, e.g. use different colors. All the details should be revealed additionally if required. This is required for unsafe/safe marks.
In addition I suppose to get rid of duplicating verdicts, such as "Bug" for an unsafe report and "Bug" for its associated mark, and duplicating problems, such as "Timeout" for an unknown report and "Timeout" for its associated mark. Perhaps I missed something and they are required...
